Hi, Cars in for its tlc and been told that it needs 2 new rear pads and discs but its only been about 10k miles since they were last replaced. Does this sound right? I know it all depends on how its driven etc but I only usually drive at weekends and not too hard. Cars a works 'S' by the way. I did notice that the discs looked a bit corroded but thought there might have been a bit more life left in them??
